General recommendations for TV LCD LED repair
It is advisable to start repairing the ROLSEN RL-24L1003F TV with a careful external examination of both internal and external elements. Visible damage to elements can sometimes indicate the direction of searching for a defect even before the necessary measurements are taken. Experienced repairmen often guess about the causes of the defect and the possible consequences, for example, by ring cracks in the soldering of the element terminals, as well as by swollen capacitors or resistors burnt out to coal dust and other external indirect signs.
In the absence of any signs of operability, when the ROLSEN RL-24L1003F does not turn on and does not signal anything with the control lamps on the panel, there is a possibility of a malfunction of the RSAG7.820.2256 Ver.D TV power module. With the same manifestations, the power regulator of the control processor on the motherboard may be faulty. When repairing a power supply, it is advisable to start diagnostics with checking the mains fuse and electrolytic capacitors of the filters of the secondary rectifiers of the converter. In the event of a break in the fuse, the cause should be sought in the power semiconductor elements of the pulse converter of the main power supply unit. First of all, it is necessary to check the diodes of the rectifier bridge of the mains voltage and the power switch (keys) of the W15 / 10 BCP56, 3N80 converter.
As a rule, switches in switching power supplies (SMPS) are quite reliable and rarely fail without reasons that should be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM microcircuit is checked by replacing it with a known good one.
If, when ROLSEN RL-24L1003F is turned on, there is no image, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the V236H1-LE2 Rev. C1 LED panel backlight LED circuit, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the common power supply.
A malfunction in the backlight circuits often occurs due to an open circuit in the power supply circuit of the LED lines. It is required to disassemble the panel and check the LEDs themselves, the ration of their conclusions, as well as the reliability of the connections in the connectors and the ration of the connector pins.
When trying to detect a break in the LED lines, it should be borne in mind that it is difficult to do this without disassembling the panel. For example, a current source is required to open PN junctions connected in series.
On the RSAG7.820.2280 / ROH motherboard, in the event of a malfunction, you should first check the operability of all stabilizers or power converters of microcircuits and, if necessary, update the software (software).
When repairing an MB board, you need to check its components MT8223LFMU, CD1517CP,. Defective elements should be replaced. If BGA chips are installed, their failure is usually localized by warming up.
If you suspect a malfunction of the HFT2-8C6 / V116H tuner, first of all, you need to make sure that there is a supply voltage of the varicaps (30-33V) at the corresponding output of the tuner, as well as other voltages supplying it.
Attention to the owners! Attempts to self-repair the ROLSEN RL-24L1003F TV are not recommended by the manufacturer and can lead to serious negative consequences!
